didn't create the 7th day sabbath for Israel ... created it for mankind ... so Jesus himself says.
Mark 2:27
Berean Study Bible
Then Jesus declared, “
The Sabbath was made for man (mankind), not man for the Sabbath.
Sorry, but teh context is with the Jewish people and not mankind in General. Jesus was saying the Sabbath was to bless men not be a burden, and that was only to the nation ISrael! If you go back to Leviticus, Exodus, and Deuteronomy as well as several other OT books, you will see that the Sabbath was part of the Covenant with Israel as a nation alone! Gentiles did not keep Sabbath, for they were not Jews! If it was binding on all mankind, one would have to conclude that at least some nation or tribe would honor it! But none of the nations know of the Sabbath because it was not commanded on man until Mt. Sinai which was for israel and their proselytes who wish to accompany them.
But the 7th day is also a type for the rest we enter when we receive Christ! We cease from our labors to gain righteousness and rest in the righteousness imputed to us by Jesus!
Here is the big passage that confirms what I say:
Exodus 31:12-18
King James Version
12 And the Lord spake unto Moses, saying,
13 Speak thou also unto the children of Israel, saying, Verily my sabbaths ye shall keep: for it is a sign between me and you throughout your generations; that ye may know that I am the Lord that doth sanctify you.
14 Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth any work therein, that soul shall be cut off from among his people.
15 Six days may work be done; but in the seventh is the sabbath of rest, holy to the Lord: whosoever doeth any work in the sabbath day, he shall surely be put to death.
16 Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant.
17 It is a sign between me and the children of Israel for ever: for in six days the Lord made heaven and earth, and on the seventh day he rested, and was refreshed.
18 And he gave unto Moses, when he had made an end of communing with him upon mount Sinai, two tables of testimony, tables of stone, written with the finger of God.
